Storage Redundancy (1 / 16): Your organization's application uses Azure GZRS storage account. You have observed that read and write operations can still continue even if an availability zone becomes unavailable or unrecoverable. How does GZRS achieve this level of data availability during an outage?
Answer:
GZRS improves the availability by storing copies of data across three Azure availability zones. So, even if one zone becomes unavailable, the data is still accessible from the other zones.
GZRS does not replicate the data synchronously three times within a single physical location in the primary region.
Replicating the data asynchronously to a secondary region is more about ensuring geographical redundancy and doesn't provide immediate availability during an outage in the primary region.
Committing a write operation to the primary location before replicating it using LRS is part of both GRS and GZRS data flow, and doesn't specifically contribute to data availability during an availability zone outage.
